This is a swamp at the bottom of a couple of the broken Queen's Way pillars for the first encounter in Hither in Wild Beyond the Witchlight - although it could double as a generic swamp with ruins.
I have, however, tried to follow the description in WBtW pretty closely - glowing pillars, fungi to climb, glowing crickets, etc.
I've also sized the pools to allow a Harengon's standing leap to clear them, but they will be a wade for most PCs, so it could cause some interesting mobility asymmetry in the battle...
This is sized for a 43" 4k mapping TV @100dpi.
